6.4 System Planning
When planning an application, attention should be paid to both system
operat ion and topology. Applicat ion requirement s and elect romagnet ic
environment characteristics should also be taken into account.
2 basic types of applications are possible: Fixed DataReader applications
and Mobile DataReader applications. A complex application that combines
DataReaders in both configurations is also possible.
The Fixed DataReader applications are applications where the DataReaders
are mounted at a fixed site. The Mobile applications are situations where
the DataReaders are mounted on vehicles for monitoring DataSeals in
transit. Mobile applications are normally implemented using the
TrackingDataReader, but may also be implemented using a DataReader
